CHARLES W. BAKE, OF CHICAGO, ILLINOIS, ASSIGNOR TO PYLE NATIONALELECTRIC HEADLIGHT COMPANY, OF CHICAGO, ILLINOIS,

'1 0 all 'ZUZZOllZ. 1' Z: may concern Be it known that I, CHARLES W.DAKE,

a citizen of the United States, residing at )hicago, in the county ofCook and State of Illinois, have invented a certain new and usefulImprovement in Motor-Generators, of which the following is aspecification.

My invention relates to improvements motor generator sets and isillustrated diagrammatically in one form in the accom panying drawings,wherein- Figure l is a side elevation in part section; Fig. 2, a detailpart section alongthe line 2--2 of Fig. 1.

Like parts are indicated by like numerals throughout the severalfigures.

The motor A which in this particular instance takes the form of theusual well known steam turbine and therefore needs no furtherdiscussion, is separated from the generator B by the hollow cylindricalhousing or sleeve C which is attached to the generator housing by thecap screw C The shaft D is provided at the end adjacent the motor withthe shoulder D against which abuts the collar D which abuts on the otherside the annular ball bearing D The sleeve 1) abuts at one end-againstthe ball bearing D and at the other end against a similar ballbearing Dwhich in turn abuts against the sleeve D. The generator hub D "s forcedon to the shaft D against the sleeve 1) tightening all the membersagainst the shoulder D by the cap D and the cap screw D The pin D floatsin the shaft 1) and in the slot D in such manner that while it preventsrotation of the hub 01; the shaft it in noWise limits it during ordinaryoperation against longitudinal movement in either direction. The bearingsleeve E surrounds the shaft D and is provided adjacent either end withthe spaced grease intercepting baille plates E E and supports at one endthe E held in position by the cap E and cap screws E the cap E beingprovided with the grease intercepting battle plates E. The sleeve Ecarries at its other end the ball bearing sleeve E slidablymountedtherein and limited in its movement by the cap E held in position by thecap screws E? and provided with the grease battle plates E The sleeve Eis provided adjacent either Specification of Letters Patent.

end with the collars G, G in opposition to the shoulders G G in thesleeve C. It will be observed that the collar G is of larger diameterthan the collar G, thus making it easy to Withdraw the sleeve E and-easyalso to machine both the sleeve and collars at one operation. The lugsGr projecting outwardly on either side from the collar G are bolted tothe lugs G projecting inwardly from the sleeve sleeve E in positiontherein. The grease cups H, H are connected by means of the passages H Hwith the grease chambers H H in which are located the ball bearings ateither end of the shaft. The grease baflie plates at either end of thebearings prevent to a great extent the waste of grease from the bearingsand any grease which does exude is drained off in any suitable mannernot shown.

It will be evident that while I have shown in my drawings an operativedevice, still many changes might be made in size, shape and arrangementof the parts without departing materially from the spirit of myinvention, and I wish therefore, that my drawings be regarded as in asense diagrammatic.

The use and operation of my device is as follows: In driving a generatorby means of a steam turbine it will at once be evident that some meansmust be had for separating the two since the turbines which arefrequently driven by steam have a tendency to heat the generator undulyif they are close together. Moreover, it is necessary that some meansfor steadying and supporting the shaft be had. I therefore provide anouter sleeve which connects the housings of the motor and of thegenerator and spaces them apart. In this sleeve I provide two inwardlyprojecting lugs or shoulders which shoulders are adapted to supportcollars on an inner bearing sleeve. This inner bearing sleeve is carrieby the collars within the shoulders and held in position therein by thetwo lugson either side bolted to lugs in the outer sleeves. By makingthe collar adjacent the motor of smaller diameter than the other, I amenabled to provide for simultaneous machining of the two bearing sleevesboth on the collar on the inner sleeve and the shoulders OIlnhlilB outersleeve. The

two annular ball bearings tin theirliier shaft C to hold theare spacedone from the other by a sleeve closely encircling the shaft and bytightening the cap'screw in the end of the shaft I am enabled to forcethe ball bearings and spacing sleeves and collars firmly togetheragainst the shoulder on the motor end of the shaft. It will be observedthat the ball bearing at the motor end of the shaft is rigidly held. in.position in the supporting sleeve but that the ball bearing collar atthe other cndis slidable therein, this to take care of any difference inexpansion which may take place between the cast iron sleeve and steelshaft and collar. The caps at either end of the sleeve hold the bearingsand shaft in position therein and limit its longitudinal motion. Greaseis forced from the grease caps from the grease passages to the annularball bearings and held therein by the batlle plates on either sidethereof in opposition to the shaft.

In order to withdraw the sleeve E it must first be turned through aslight angle until the lugs (i come out of line with the lugs (i whenthe sleeve may be withdrawn.
